Description

Academic Photography Assistants {Photography-aiding Tool for Science Education}

The present invention relates to a teaching aid for science learning, and more particularly, in order to enable the learner to easily understand the scientific principle of the center of gravity through the principle of preventing shaking during shooting of the camera by moving the center of gravity of the camera to the outside of the camera. A teaching assistant teaching aid that makes it easy to assemble.

The sciences that elementary and secondary students encounter are fundamental and include many very important processes that lead to a basic understanding of science. When studying these science subjects, if you do not understand the principles of science correctly and memorize the study, you lose interest in the increasingly complicated laws of science. Eventually, some experimental tools were introduced to help understand these early science principles, but there is no way for all students to understand the results of their own assembly and experimentation.

In particular, when studying the scientific principle of the center of gravity, it can be difficult to understand the principle of the center of gravity because the center of gravity is the virtual center of gravity that is not visible to the naked eye.

The present invention is to solve the above problems, an object of the present invention is to directly and learners to understand the scientific principle of the center of gravity easily and fun through the principle of the shooting aids to prevent shaking when shooting the camera It is to provide a teaching assistant teaching aid that can be easily assembled and used.

Learning assistant for teaching aid according to the present invention for achieving the above object, the handle insertion hole is formed in the lower surface, the fixing groove is fitted into the upper surface and fixed to one side of the fixing groove and the fixing groove. A mount member having an extended guide groove formed therein; A balance bar having one end coupled to and fixed to the mount member by a fastening means, and having a curved bar shape; A weight member detachably coupled to the distal end of the balance bar; Two sets of support members inserted into both sides of the guide groove of the mount member and slidable in the lateral direction along the guide groove, and supporting the imaging apparatus while being in contact with both side portions of the photographing apparatus inserted into the fixing groove of the mount member. Wow; The upper end portion is characterized in that it comprises a handle member which is inserted into the handle insertion hole of the mount member so as to be relatively rotatable.

According to the present invention, the learner can easily assemble each component directly to produce a shooting assistant teaching aid, and the shooting assistant equipped with a photographing device (for example, a camera or a mobile communication terminal) to shoot the image You can check and learn the principle of center of gravity.

The support members 40 are made of a synthetic resin material such as EVA, similar to the mount member 10, and have a substantially 'c' shape so that the lower end is inserted into the guide groove 16 of the upper plate 12. After the movement along the guide groove 16 is adjusted to close contact with the side of the photographing device (1).

5 and 6, the handle member 50 is a hollow shaft-shaped handle shaft 51 having a predetermined length so that the user can hold by hand, and the screw on the upper end of the handle shaft 51 The inner ring 52 coupled by the 54 and maintaining a constant distance from the outer circumferential surface of the handle shaft 51, and the screw 55 while maintaining a constant distance with the inner ring 52 on the outer side of the inner ring 52 It is coupled to the inner ring 52 by the outer ring 53 is inserted into the handle insertion hole 14 of the mount member 10 is configured to include. Here, the screws 54 connecting the inner ring 52 to the handle shaft 51 and the screws 55 connecting the outer ring 53 to the inner ring 52 are disposed at 90 degree intervals from each other. . Accordingly, the handle shaft 51 is rotatable about the inner ring 52 about the two screws 54 connected to the inner ring 52 and the inner ring 52, and the inner ring 52 is the outer ring 53. ) And the two screws 55 connected to each other can be rotated about the outer ring 53.

If described in detail the assembly and operation of the learning aids teaching aid configured as described above are as follows.

First, as shown in FIG. 3, one end of the balance bar 20 is positioned on the base plate 11, and the base of the balance bar 20 is passed while passing the cable tie 23 through the tie through hole 11b. Fix to the plate (11). At this time, the bent end of the balance bar 20 is coupled to the base plate 11 while being plugged.

Subsequently, as shown in FIG. 4, after the upper plates 12 are positioned on the base plate 11, the fastening block 13 is inserted through the upper coupling holes 12a and the lower coupling holes 11a. The base plate 11 and the upper plate 12 are coupled to each other by the fastening block 13 to be integrated. At this time, the upper plates 12 are spaced apart from each other at regular intervals, and the space between the spaced apart is a fixed groove 15 into which the imaging device 1, for example, a mobile communication terminal such as a mobile phone or a smartphone is inserted.

Subsequently, the lower ends of the support members 40 are inserted into the guide grooves 16 of the upper plate 12 to be coupled to each other.

Next, as shown in FIGS. 5 and 6, the inner ring 52 is aligned with the upper end of the handle shaft 51, and the screwing hole 52a and the handle shaft 51 of the inner ring 52 are aligned with each other. The inner ring 52 is connected to the handle shaft 51 by fastening the screw 54 through the screw fastening hole 51a. Subsequently, the outer ring 53 is aligned with the outer side of the inner ring 52, and the screw 55 is disposed through the screwing hole 53a of the outer ring 53 and the screwing hole 52b of the inner ring 52. ) To connect the outer ring 53 to the inner ring 52.

Then, the assembled handle member 50 is inserted into the handle insertion hole 14 of the base plate 11 under the base plate 11, as shown in FIG. At this time, since the inner diameter of the handle insertion hole 14 substantially matches the outer diameter of the outer ring 53 of the handle member 50, the outer ring 53 of the handle member 50 is connected to the handle insertion hole 14. Fits snugly and joins.

Subsequently, as shown in FIG. 8, the wire 33 is connected through a hole (not shown) of the first casing 31a of the weight member 30, and then the first casing 31a and the second casing.
